[W]hile "I'm Gonna Be (500 Miles)" does a great job of laying out the folk-rockers' intentions to complete the full thou', it is lousy about providing the specifics of their journey. What direction are they walking, for instance – south toward London, or north to the frigid, rocky shores of the far Highlands? Then there's the problem that if they walked 500 x 2 miles in a straight line from any point in the U.K., they'd hit water. Would they stop and reconsider their travel plans (buy a jet-ski, perhaps)? Or would they keep on walking straight into the briny waves, plodding along the ocean floor to some remote island where their seagull poo-splattered lover is waiting?

It's a catchy song, but it leaves so many questions! Fortunately, there's a guy hard on the case to unravel its mysteries. Kenneth Field is a 40-something cartographic product engineer in Southern California who's made a fun map showing all the places the band could walk to in a 360 degree field if they began in Leith, the birthplace of twin-brother singers Craig and Charlie Reid.
